בראשית, פרק כ״א, פסוק ל״ד

Abraham's time in the land of the Philistines marks a long and significant chapter in his life, serving as the quiet period right before his greatest test. During this time, he did not establish a permanent settlement but lived as a stranger [ביאור שטיינזלץ]. Walking the length and breadth of the land as an outsider served a dual purpose: it allowed him to spread the name of God and began the fulfillment of the prophecy that his offspring would be strangers in a land not their own, a reality that started taking shape with the birth of Isaac [מלבי״ם].

The exact location of this extended stay is a matter of discussion. Some consider the area of Beersheba to be part of the land of the Philistines [רד״ק]. Others maintain that Beersheba was a separate territory, suggesting that Abraham lived in the Philistine city of Gerar for years before eventually moving to Beersheba, where he planted trees and made his home [ביאור יש״ר]. Regardless of the exact borders, this prolonged period of residence was made possible by the peace treaty he made with Abimelech, which granted him security and removed any fear of human threats [רד״ק].

The length of this stay is subject to careful chronological analysis. The primary approach among commentators is that this period is compared to Abraham's previous residence in Hebron. He had lived in Hebron for twenty-five years, from the age of seventy-five until he was ninety-nine, at which point he left out of shame over the actions of Lot in Sodom. Because it is understood that his stay in the Philistine territory was longer, the conclusion is that he lived there for twenty-six years [רש״י]. However, some point out that this calculation might be incomplete, as it remains unknown exactly how much time Abraham spent wandering the land before he originally settled in Hebron [ברכת אשר על התורה].

The effort to calculate these twenty-six years stems from a need to understand the timeline leading up to the Binding of Isaac. The story of the Binding follows this period in a way that usually implies an immediate sequence of events. Yet, the chronological calculation reveals a twelve-year gap between the end of Abraham's time in the land of the Philistines and the Binding of Isaac. This significant delay demonstrates that the Binding did not occur right after the treaty with Abimelech. Instead, it was prompted by entirely different matters that took place during those intervening years, such as the accusations of Satan or the claims made by Ishmael [מזרחי, שפתי חכמים].
